To start with, i commend you on your willingess to learn. That's the
key success factor around here. :-)

Um, not quite. Let me try to explain, though Tantek or Ryan could
probably do better. First of all, you *are* correct in that the
preferred method is to reuse *existing* HTML semantics; the URN trick
is rather clever, I must admit.
However, there's a deeper design principle at stake: human-
readability. The one concern I have with URNs -- even more than the
fact that they are deprecated -- is that they are pretty much opaque,
and somewhat confusing.
To better match how humans handle HTML, we leverage CSS class name,
as seen in hCalendar and hCard:
To be sure, there is some risk:

However, here's the point I think you are missing. The underlying
premise of microformat as class names is that they *naturally*
reflect the underlying semantics. Hence the concept 'semantic salt'
-- bringing out that which is latent. If those class names do in
fact reflect what the designer *means* by the use of those elements,
i) this is in fact the optimal way to identify those styles
ii) any transformation that obliterates that metadata will
(inevitably) lose information
That isn't to say that my proposal is perfect -- it's a very crude
first approximation. However, I hope this at least gives you a bit
more clue about the parameter space we're trying to explore, and our
criteria for success.
Again, thanks again for your thoughtful post and your willingness to
